'Game of Thrones' season 4 left us a bit in the Red Waste with regard to its Comic-Con 2013 panel, eschewing the mammoth casting reveals of the previous year in favor of a retrospective for those lost within the first three seasons. In spite of that void however, another major season 4 player has finally been cast with 'Rome' star Indira Varma, that of Prince Oberyn Martell (Pedro Pascal)'s main squeeze, Ellaria Sand!

Entertainment Weekly first revealed the casting, which follows the George R.R. Martin character's book description as a "sexually adventurous paramour," and presumably mother to "Red Viper" Oberyn Martell's bastard daughters, known as the "Sand Snakes." Previously, Varma was best known for her work in HBO's 'Rome,' which also featured current 'Game of Thrones' star Ciaran Hinds (Mance Rayder.)

Varma is the latest high profile guest-star to be announced for the new season debuting in 2014, following that of Pedro Pascal himself and 'Sherlock' writer/star Mark Gatiss. Intriguingly, HBO has yet to reveal any details of Gatiss' role, though fans have already put forth plenty of speculation.
